RESUMEN
Objective: Chronic limb threatening ischemia is the final stage of peripheral arterial disease. Current treatment is based on revascularization to preserve the leg. In the older, hospitalized chronic limb threatening ischemia patient, delirium is a frequent and severe complication after revascularization. Delirium leads to an increased length of hospital stay, a higher mortality rate and a decrease in quality of life. Currently, no specific guidelines to prevent delirium in chronic limb threatening ischemia patients exist. We aim to evaluate the effect of a multicomponent, multidisciplinary prehabilitation program on the incidence of delirium in chronic limb threatening ischemia patients ≥65 years. Design: A prospective observational cohort study to investigate the effects of the program on the incidence of delirium will be performed in a large teaching hospital in the Netherlands. This manuscript describes the design of the study and the content of this specific prehabilitation program. Methods: Chronic limb threatening ischemia patients ≥65 years that require revascularization will participate in the program. This program focuses on optimizing the patient's overall health and includes delirium risk assessment, nutritional optimization, home-based physical therapy, iron infusion in case of anaemia and a comprehensive geriatric assessment in case of frailty. The primary outcome is the incidence of delirium. Secondary outcomes include quality of life, amputation-free survival, length of hospital stay and mortality. Exclusion criteria are the requirement of acute treatment or patients who are mentally incompetent to understand the procedures of the study or to complete questionnaires. A historical cohort from the same hospital is used as a control group. Discussion: This study will clarify the effect of a prehabilitation program on delirium incidence in chronic limb threatening ischemia patients. New insights will be obtained on optimizing a patient's preoperative mental and physical condition to prevent postoperative complications, including delirium. Trial: This protocol is registered at the Netherlands National Trial Register (NTR) number: NL9380.

BACKGROUND: Chronic limb-threatening ischemia (CLTI) has a high mortality and amputation risk even after revascularization. Owing to an aging population the incidence of peripheral arterial disease is rising. However, the current age distribution in patients with CLTI and the impact of age on outcomes remains unclear. For this reason we performed an age-dependent analysis of mortality, morbidity, and amputation-free survival after open surgical revascularization (OSR) and endovascular revascularization therapy (ERT) with identification of risk factors for mortality. Standardized mortality ratios (SMR) were calculated, comparing observed deaths in the study population to expected deaths based on age and gender specific mortality rates of the overall Dutch population. METHODS: Patients revascularized for the first episode of CLTI between 2013 and 2018 were included in this multicenter retrospective cohort study. The cohort was divided into 2 treatment groups (OSR and ERT) who were each stratified in 3 age groups: early age group < 65 years (G1), middle age group 65-74 years (G2), and elderly age group ≥ 75 years (G3). RESULTS: During the study period 274 limbs (43.9%) were treated with OSR and 350 limbs (56.1%) with ERT. The young population (G1) is only a small part of the whole CLTI population, namely for OSR 22% and ERT 18%. The risk profile of the early age group was characterized by male gender and smoking, whereas the elderly age group was characterized by poor arterial runoff, tissue loss, hypertension, hypercholesterolemia, chronic kidney disease, history of heart disease, chronic obstructive pulmonary disease, and cerebrovascular disease. One year amputation rates were similar between the age groups. However, significantly higher one-year mortality rates were observed in patients ≥ 75 years in comparison to the low mortality rates in patients < 75 years (OSR: G3 19.8% vs. G2 7.1% and G1 6.7%, P = 0.006; ERT: G3 30.7% vs. G2 12.7% and G1 7.8%, P = 0.001). The SMR in this elderly group equaled 3.72 after OSR and 4.04 after ERT. Independent risk factors for mortality after OSR were age, hazard ratio (HR) 1.03 (95% confidence interval [CI] 1.01-1.06; P = 0.006), preoperative hemoglobin level (HR 0.79; 95% CI 0.67-0.92; P = 0.003), tissue loss (HR 1.85; 95% CI 1.22-2.79; P = 0.004), cardiac history (HR 1.56; 95% CI 1.06-2.30; P = 0.024), and development of postoperative delirium (HR 2.75; 95% CI 1.61-4.71; P < 0.001). After ERT we identified age, HR 1.06 (95% CI 1.04-1.08; P < 0.001); preoperative hemoglobin level, HR 0.75 (95% CI 0.65-0.87; P < 0.001); tissue loss, HR 1.71 (95% CI 1.15-2.53; P = 0.008); history of chronic obstructive pulmonary disease, HR 1.99 (95% CI 1.43-1.79; P < 0.001); history of cerebrovascular accident (CVA), HR 1.55 (95% CI 1.09-2.21; P = 0.015); the development of postoperative pneumonia, HR 2.27 (95% CI 1.24-4.16; P = 0.008); postoperative acute kidney injury (AKI), HR 2.42 (95% CI 1.29-4.54; P = 0.006); and postoperative CVA, HR 8.17 (95% CI 1.96-34.15; P = 0.004) as risk factors. CONCLUSIONS: The current CLTI population consists mostly of elderly patients and only a small part is younger than 65 years. This shift in the population is important because increasing age is associated with considerable higher one-year mortality rates regardless of the method of revascularization in patients with CLTI. The mortality rates in the elderly group are 3 to 4 times larger than expected in the general population. In relation to the high mortality of the elderly patient, we assume that interventions to prevent postoperative delirium and correct preoperative anemia may be warranted as they appear to be independent risk factors for mortality.

AIMS: This study aimed to assess the sex-specific distribution of heart failure (HF) with preserved, mid-range, and reduced ejection fraction across three health care settings. METHODS AND RESULTS: In this descriptive observational study, we retrieved the distribution of HF types [with reduced ejection fraction (HFrEF), mid-range ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF)] for men and women between 65 and 79 years of age in three health care settings from a single country: (i) patients with screening-detected HF in the high-risk community (i.e. those with shortness of breath, frailty, diabetes mellitus, and chronic obstructive pulmonary disease) from four screening studies, (ii) patients with confirmed HF from primary care derived from a single observational study, and (iii) patients with confirmed HF from outpatient cardiology clinics participating in a registry. Among 1407 patients from the high-risk community, 288 had screen-detected HF (15% HFrEF, 12% HFmrEF, 74% HFpEF), and 51% of the screen-detected HF patients were women. In both women (82%) and men (65%), HFpEF was the most prevalent HF type. In the routine general practice population (30 practices, 70 000 individuals), among the 160 confirmed HF cases, 35% had HFrEF, 23% HFmrEF, and 43% HFpEF, and in total, 43% were women. In women, HFpEF was the most prevalent HF type (52%), while in men, this was HFrEF (41%). In outpatient cardiology clinics (n = 34), of the 4742 HF patients (66% HFrEF, 15% HFmrEF, 20% HFpEF), 36% were women. In both women (56%) and men (71%), HFrEF was the most prevalent HF type. CONCLUSIONS: Both HF types and sex distribution vary considerably in HF patients of 65-79 years of age among health care settings. From the high-risk community through to general practice to the cardiology outpatient setting, there is a shift in HF type from HFpEF to HFrEF and a decrease in the proportion of HF patients that are women.

OBJECTIVE: To determine the safety of the non-intubated and intubated adenotonsillectomy by the Sluder method in children DESIGN: Retrospective database study METHOD: We compared the data of adenotonsillectomy by the Sluder method in children until thirteen years of two teaching hospitals from 2014 until 2017. In the Amphia Hospital the procedure was performed without endotracheal tube placement and without perioperative opioids, in the Haga Hospital the patients were intubated and received perioperative opioids. Primary outcome was reoperation for postoperative haemorrhage. Secondary outcomes included desaturation (saturation ≤ 90% > 1 min), severe hypoxemia (saturation ≤ 85% for ≥ 5 min), airway complications, bradycardia, total postoperative haemorrhages, use of rescue medication, hospital readmission and 30-day mortality. RESULTS: A total of 1370 patients were analysed: 1267 adenotonsillectomies and 103 tonsillectomies. Median operation time was 7 minutes in the non-intubated group versus 12 minutes in the intubated group. The primary outcome occurred in thirteen patients in the group without intubation (2.2%) and eleven times in the group with intubation (1.4%). There was one case of severe hypoxemia in the group without intubation. Desaturation occurred mostly in the group without intubation (26.4%) for a short time (median 0 min, interquartile range 0-1). Bradycardia was seen more in the group with intubation (4.1% vs 2.2%). CONCLUSION: The incidence of postoperative haemorrhage and severe airway complications after adenotonsillectomy by the Sluder method with and without endotracheal tube placement in both groups was comparable.

OBJECTIVES: To determine the impact of the first lockdown in the Netherlands' measures during the COVID-19 pandemic on the number and type of trauma-related injuries presenting to the emergency department (ED). DESIGN: A single-centre retrospective cohort study. SETTING: A level 2 trauma centre in Breda, The Netherlands. PARTICIPANTS: All patients with trauma seen at the ED between 11 March and 10 May 2020 (the first Dutch lockdown period) were included in this study. Comparable groups were generated for 2019 and 2018. MAIN OUTCOME MEASURES: Primary outcomes were the total number of patients with trauma admitted to the ED and the trauma mechanism. Secondary outcomes were triage categories, time of ED visit, trauma severity (Injury Severity Score (ISS) >12), anatomical region of injury and treatment. RESULTS: A total of 4674 patients were included in this study. During the first months of the COVID-19 pandemic, there was a decrease of 32% in traumatic injuries at the ED (n=1182) compared with the previous years 2019 (n=1717) and 2018 (n=1775) (p<0.001). Sports-related injuries decreased most during the lockdown (n=164) compared with 2019 (n=386) and 2018 (n=367) (p<0.001). We observed more frequent injuries due to a fall from standing height (p<0.001) and work-related injuries (p<0.05). The mean age was significantly higher (mean 48 years vs 42 and 43 years). There was no difference in anatomical place of injury or ISS >12. The amount of patients admitted for emergency surgery was significantly higher (14.6% vs 9.4%; 8.6%, p<0.001). Seven patients (0.6%) tested positive for COVID-19. CONCLUSIONS: Measures taken in the COVID-19 outbreak result in a predictable decrease in the total number of patients with trauma, especially sports-related trauma. Although the trauma burden on the emergency room appears to be lower, more people have been admitted for trauma surgery, possibly due to increased throughput in the operating theatres.

PURPOSE: The extended role of breast-conserving surgery (BCS) in the neoadjuvant setting may raise concerns on the oncologic safety of BCS compared to mastectomy. This study compared long-term outcomes after neoadjuvant chemotherapy (NAC) between patients treated with BCS and mastectomy. METHODS: All breast cancer patients treated with NAC from 2008 until 2017 at the Amphia Hospital (the Netherlands) were included. Disease-free and overall survival were compared between BCS and mastectomy with survival functions. Multivariable Cox proportional hazard regression was performed to determine prognostic variables for disease-free survival. RESULTS: 561 of 612 patients treated with NAC were eligible: 362 (64.5%) with BCS and 199 (35.5%) with mastectomy. Median follow-up was 6.8 years (0.9-11.9). Mastectomy patients had larger tumours and more frequently node-positive or lobular cancer. Unadjusted five-year disease-free survival was 90.9% for BCS versus 82.9% for mastectomy (p = .004). Unadjusted five-year overall survival was 95.3% and 85.9% (p < .001), respectively. In multivariable analysis, clinical T4 (cT4) (HR 3.336, 95% CI 1.214-9.165, p = .019) and triple negative disease (HR 5.946, 95% CI 2.703-13.081, p < .001) were negative predictors and pathologic complete response of the breast (HR 0.467, 95% CI 0.238-0.918, p = .027) and axilla (HR 0.332, 95% CI 0.193-0.572, p = .001) were positive predictors for disease-free survival. Mastectomy versus BCS was not a significant predictor for disease-free survival when adjusted for the former variables (unadjusted HR 2.13 (95%CI: 1.4-3.24), adjusted HR 1.31 (95%CI: 0.81-2.13)). In the BCS group, disease-free and overall survival did not differ significantly between cT1, cT2 or cT3 tumours. CONCLUSION: BCS does not impair disease-free and overall survival in patients treated with NAC. Tumour biology and treatment response are significant prognostic indicators.

BACKGROUND: The aim of this study is to investigate the impact of the coronavirus disease 2019 (COVID-19) lockdown period on the number and type of vascular procedures performed in the operating theater. METHODS: A total of 38 patients who underwent 46 vascular procedures during the lockdown period of March 16th until April 30th, 2020, were included. The control groups consisted of 29 patients in 2019 and 54 patients in 2018 who underwent 36 and 66 vascular procedures, respectively, in the same time period. Data were analyzed using SPSS Statistics. RESULTS: Our study shows that the lockdown during the COVID-19 pandemic resulted in a significant increase in the number of major amputations (42% in 2020 vs. 18% and 15% in 2019 and 2020, respectively; P-value 0.019). Furthermore, we observed a statistically significant difference in the degree of tissue loss as categorized by the Rutherford classification (P-value 0.007). During the lockdown period, patients presented with more extensive ischemic damage when than previous years. We observed no difference in vascular surgical care for patients with an aortic aneurysm. CONCLUSIONS: Measurements taken during the lockdown period have a significant effect on non-COVID-19 vascular patient care, which leads to an increased severe morbidity. In the future, policy makers should be aware of the impact of their measurements on vulnerable patient groups such as those with peripheral arterial occlusive disease. For these patients, medical care should be easily accessible and adequate.

OBJECTIVES: In cardiac surgery, adequate heparinization is necessary to prevent thrombus formation in the cardiopulmonary bypass (CPB). To counteract the heparin effect after weaning from CPB, protamine is administered. The optimal protamine/heparin ratio is still unknown. METHODS: In this before-after study, we evaluated the effect of a 0.6/1-protamine/heparin ratio implementation as of May 2017 versus a 0.8/1-protamine/heparin ratio on the 12-h postoperative blood loss and the amount of blood and blood component transfusions (fresh frozen plasma, packed red blood cells, fibrinogen concentrate, platelet concentrate and prothrombin complex concentrate) after cardiac surgery. A total of 2051 patients who underwent cardiac surgery requiring CPB between May 2016 and May 2018 were included. RESULTS: In the 0.6/1-protamine/heparin ratio group, only 28.8% of the patients received blood component transfusion, compared to 37.9% of the patients in the 0.8/1-ratio group (P < 0.001). The median 12-h postoperative blood loss was 230 ml (interquartile range 140-320) in the 0.6/1-ratio group versus 260 ml (interquartile range 155-365) in the 0.8/1-ratio group (P < 0.001). CONCLUSIONS: A 0.6/1-protamine/heparin ratio after weaning from CPB is associated with a significantly reduced 12-h postoperative blood loss and blood components transfusion.

OBJECTIVES: According to new Dutch guidelines for rectal cancer, MRI-defined tumour stage determines whether preoperative radiotherapy is indicated. Therefore, we sought to evaluate if preoperative MRI accurately predicts the indication for neoadjuvant treatment in rectal cancer cases in daily practice according to the new Dutch guidelines. METHODS: Data for all rectal cancer patients who underwent mesorectal excision in our hospital, between January 2011 and January 2018 were collected retrospectively. We compared histopathologic outcome with tumour staging on preoperative MRI for patients who received no radiotherapy prior to resection or short-course radiotherapy directly followed by resection. RESULTS: Of 223 patients treated according to the old guidelines, 94% received neoadjuvant therapy. Of 301 patients treated according to the new guidelines, only 49% did. Under the old guidelines, MRI predicted lymph node metastases with a sensitivity of 74.2% and a specificity of 52.6%. With the new guidelines, sensitivity was 47.5% and specificity was 77.3%. The new guidelines resulted in 45% more patients not being exposed to disadvantages of radiotherapy, but 13% of all patients were undertreated. CONCLUSIONS: Concordance between clinical lymph node staging on preoperative MRI and histopathologic staging is limited, resulting in many rectal cancer patients not receiving adequate neoadjuvant therapy.

Major Depressive Disorder (MDD) is a heterogeneous disorder with a considerable symptomatic overlap with other psychiatric and somatic disorders. This study aims at providing evidence for association of a set of serum and urine biomarkers with MDD. We analyzed urine and serum samples of 40 MDD patients and 47 age- and sex-matched controls using 40 potential MDD biomarkers (21 serum biomarkers and 19 urine biomarkers). All participants were of Caucasian origin. We developed an algorithm to combine the heterogeneity at biomarker level. This method enabled the identification of correlating biomarkers based on differences in variation and distribution between groups, combined the outcome of the selected biomarkers, and calculated depression probability scores (the "bio depression score"). Phenotype permutation analysis showed a significant discrimination between MDD and euthymic (control) subjects for biomarkers in urine (Pâ¯<â¯.001), in serum (Pâ¯=â¯.02) and in the combined serum plus urine result (Pâ¯<â¯.001). Based on this algorithm, a combination of 8 urine biomarkers and 9 serum biomarkers were identified to correlate with MDD, enabling an area under the curve (AUC) of 0.955 in a Receiver Operating Characteristic (ROC) analysis. Selection of either urine biomarkers or serum biomarkers resulted in AUC values of 0.907 and 0.853, respectively. Internal cross-validation (5-fold) confirmed the association of this set of biomarkers with MDD.

PURPOSE: It is unclear whether obstructing colorectal cancer (CRC) has a worse prognosis than non-obstructing CRC. Of CRC patients, 10-28% present with symptoms of acute obstruction. Previous studies regarding obstruction have been primarily based on short-term outcomes, risk factors and treatment modalities. With this study, we want to determine the long-term survival of patients presenting with acute obstructive CRC. METHODS: This single-centre observational retrospective cohort study includes all CRC patients who underwent surgery between December 2004 and 2010. Patients were divided into two groups: ileus and no ileus. Survival analyses were performed for both groups. Additional survival analyses were performed in patients with and without synchronous metastases. The primary outcome was survival in months. RESULTS: A total of 1236 patients were included in the analyses. Ileus occurred in 178 patients (14.4%). The 5-year survival for patients with an ileus was 32% and without 60% (P < 0.01). In patients without synchronous metastases, survival with and without an ileus was 40.9 and 68.4%, respectively (P < 0.01). If ileus presentation was complicated by a colon blowout, 5-year survival decreased to 29%. No significant difference was found in patients with synchronous metastases. Survival at 5 years in this subgroup was 10 and 12% for patients with and without an ileus, respectively (P = 0.705). CONCLUSIONS: Patients with obstructive CRC have a reduced short-term overall survival. Also, long-term overall survival is impaired in patients who present with acute obstructive CRC compared to patients without obstruction.

OBJECTIVE: Heart failure (HF) often coexists in atrial fibrillation (AF) but is frequently unrecognised due to overlapping symptomatology. Furthermore, AF can cause elevated natriuretic peptide levels, impairing its diagnostic value for HF detection. We aimed to assess the prevalence of previously unknown HF in community-dwelling patients with AF, and to determine the diagnostic value of the amino-terminal pro B-type natriuretic peptide (NTproBNP) for HF screening in patients with AF. METHODS: Individual participant data from four HF-screening studies in older community-dwelling persons were combined. Presence or absence of HF was in each study established by an expert panel following the criteria of the European Society of Cardiology. We performed a two-stage patient-level meta-analysis to calculate traditional diagnostic indices. RESULTS: Of the 1941 individuals included in the four studies, 196 (10.1%) had AF at baseline. HF was uncovered in 83 (43%) of these 196 patients with AF, versus 381 (19.7%) in those without AF at baseline. Median NTproBNP levels of patients with AF with and without HF were 744 pg/mL and 211 pg/mL, respectively. At the cut-point of 125 pg/mL, sensitivity was 93%, specificity 35%, and positive and negative predictive values 51% and 86%, respectively. Only 23% of all patients with AF had an NTproBNP level below the 125 pg/mL cut-point, with still a 13% prevalence of HF in this group. CONCLUSIONS: With a prevalence of nearly 50%, unrecognised HF is common among community-dwelling patients with AF. Given the high prior change, natriuretic peptides are diagnostically not helpful, and straightforward echocardiography seems to be the preferred strategy for HF screening in patients with AF.

OBJECTIVE: Since the implementation of new guidelines for rectal cancer in The Netherlands in April 2014, clinical stage as seen at preoperative MRI indicates whether neoadjuvant therapy is necessary before rectal cancer surgery. Therefore, the importance of correct MRI interpretation has increased. The aim of this study was to evaluate the completeness of MRI reports of rectal cancer and the effect of implementation of the new guidelines and standardized reporting on the completeness of these reports. MATERIALS AND METHODS: Data were collected from all patients who consecutively underwent rectal cancer surgery at one hospital between January 2011 and July 2017. Data were extracted from electronic patient records. RESULTS: The study included 492 MRI examinations. Before implementation of the new guidelines, a median of 4 of 10 items (interquartile range [IQR], 3-6 items) were described in each MRI report. After implementation of the new guidelines, the number of items described improved significantly (median, 7 items; IQR, 6-8 items; p < 0.001). Implementation of a standardized report led to further significant improvement (median, 9 items; IQR, 9-10 items; p < 0.001). The items scored most frequently were distance between the tumor and the anal verge (85.6%) and length of the tumor (87.6%). The items scored least were presence or absence of extramural venous invasion (21.1%) and morphologic features of the tumor (24.6%). CONCLUSION: Implementation of a standardized protocol and a standardized reporting system for MRI in preoperative staging of rectal cancer results in a more complete MRI report.

Background Prevalence of undetected heart failure in older individuals is high in the community, with patients being at increased risk of morbidity and mortality due to the chronic and progressive nature of this complex syndrome. An essential, yet currently unavailable, strategy to pre-select candidates eligible for echocardiography to confirm or exclude heart failure would identify patients earlier, enable targeted interventions and prevent disease progression. The aim of this study was therefore to develop and validate such a model that can be implemented clinically. Methods and results Individual patient data from four primary care screening studies were analysed. From 1941 participants >60 years old, 462 were diagnosed with heart failure, according to criteria of the European Society of Cardiology heart failure guidelines. Prediction models were developed in each cohort followed by cross-validation, omitting each of the four cohorts in turn. The model consisted of five independent predictors; age, history of ischaemic heart disease, exercise-related shortness of breath, body mass index and a laterally displaced/broadened apex beat, with no significant interaction with sex. The c-statistic ranged from 0.70 (95% confidence interval (CI) 0.64-0.76) to 0.82 (95% CI 0.78-0.87) at cross-validation and the calibration was reasonable with Observed/Expected ratios ranging from 0.86 to 1.15. The clinical model improved with the addition of N-terminal pro B-type natriuretic peptide with the c-statistic increasing from 0.76 (95% CI 0.70-0.81) to 0.89 (95% CI 0.86-0.92) at cross-validation. Conclusion Easily obtainable patient characteristics can select older men and women from the community who are candidates for echocardiography to confirm or refute heart failure.

BACKGROUND: The use of magnetic resonance imaging (MRI) in primary care is under debate, and the majority of GPs have no experience with MRI. OBJECTIVES: To examine for which patients with knee injury an MRI is ordered and does direct access to MRI in primary care influence the GP referral to an orthopaedic surgeon? METHODS: Consecutive patients with knee injury who underwent an MRI examination ordered by their GP were included. On the application form for MRI, the GPs indicated their referral intention in advance, as if MRI had not been available. Six months after the MRI scan, written interviews with the GPs were used to collect data on referrals and orthopaedic intervention. The number of patients finally referred to an orthopaedic surgeon in secondary care after MRI was compared with the number of intended referrals. RESULTS: Of the 588 included, GPs referred fewer patients to the orthopaedic surgeon after receiving the MRI results than they would have done prior to MRI (60% versus 82.8%, P < 0.0001). The reduction was 16.1% for patients older than 50 years and 28.1% for patients younger than 50 years. Orthopaedic intervention was performed in 62.9% of all referred patients. Of the 101 patients whom the GP did not intend to refer prior to MRI, 48 were referred to an orthopaedic surgeon based on the MRI findings. CONCLUSION: In patients with knee injury, direct access to MRI of the knee in a primary care setting significantly reduced referrals to an orthopaedic surgeon. LEVEL OF EVIDENCE: Three prospective cohort.

BACKGROUND: Heart failure (HF), especially with preserved ejection fraction (HFpEF) is common in older patients with type 2 diabetes (T2DM), but often not recognized. Early HF detection in older T2DM patients may be worthwhile because treatment may be initiated in an early stage, with clear beneficial treatment in those with reduced ejection fraction (HFrEF), but without clear prognostic beneficial treatment in those with HFpEF. Because both types of HF may be uncovered in older T2DM, screening may improve health outcomes at acceptable costs. We assessed the cost-effectiveness of five screening strategies in patients with T2DM aged 60 years or over. METHODS: We built a Markov model with a lifetime horizon based on the prognostic results from our screening study of 581 patients with T2DM, extended with evidence from literature. Cost-effectiveness was calculated from a Dutch healthcare perspective as additional costs (Euros) per additional quality-adjusted life-year (QALY) gained. We performed probabilistic sensitivity analysis to assess robustness of these outcomes. Scenario analyses were performed to assess the influence of the availability of effective treatment of heart failure with preserved ejection fraction. RESULTS: For willingness to pay values in the range of 6050/QALY-31,000/QALY for men and 6300/QALY-42,000/QALY for women, screening-based checking the electronic medical record for patient characteristics and medical history plus the assessment of symptoms had the highest probability of being cost-effective. For higher willingness-to-pay values, direct echocardiography was the preferred screening strategy. Cost-effectiveness of all screening strategies improved with the increase in effectiveness of treatment for HFpEF. CONCLUSIONS: Screening for HF in older community-dwelling patients with T2DM is cost-effective at the commonly used willingness-to-pay threshold of 20.000/QALY by checking the electronic medical record for patient characteristics and medical history plus the assessment of symptoms. The simplicity of such a strategy makes it feasible for implementation in existing primary care diabetes management programs.

OBJECTIVE: To determine how often vitamin D deficiency occurs in the populations of a city, the countryside and urbanised areas of the countryside, and also the influence of the seasons. DESIGN: Cross-sectional study carried out in the winter and summer of 2013. Trend analysis from requests for determination of vitamin D levels by general practitioners between January 2010 and August 2012. METHOD: In a random sample survey of all blood samples received by SHL-Groep (diagnostic center for primary care) between 21-01-2013 - 10-03-2013 (winter period) and 01-08-2013 - 30-08-2013 (summer period), Vitamin D levels of the residual material were measured. We reported the results by age group, gender and postal code area in the following areas: The Hague (city), Province of Zeeland (countryside) and West Brabant (urbanised countryside). In addition, the average vitamin D concentration obtained from all the requests for determination of vitamin D levels between January 2010 and August 2012 was measured against the time of year. RESULTS: During the winter period 58.8% of the 2503 participants had a vitamin D serum concentration of < 50 nmol/l (The Hague: 65.6%; Zeeland: 50.9%). A total of 29.9% had vitamin D levels of < 30 nmol/l. In men under the age of 50 years, this was 38.2%. Of the 1910 people tested during the summer, 35.4% had a vitamin D level of < 50 nmol/l (The Hague: 43.7%; Zeeland: 33.5%). 11.6% had a vitamin D level < 30 nmol/l. General practitioners requested the vitamin D levels of 50,441 patients. The average vitamin D level varies considerably with the seasons. CONCLUSION: Vitamin D deficiency occurs frequently, even in relatively young people and more so in cities than in the countryside. The average vitamin D concentration varies with the seasons.
